On the contrary. Trump is exactly the dynamite needed to hoist his supporters by their own petard, in the eyes of the vastly larger majority who voted against him.
Remember he rather significantly lost the popular vote. He "won" the election only because of (1) very large-scale Russky meddling in our electoral processes and (2) the long-outdated stupidities of construction of the Electoral College, whose real historical basis is very extremely racist indeed. Look it up.
